i went outside to my backgarden and my rabbit turned into a monster and tried to eat me
Dreaming of a pet that turns into a monster may suggest that there is something in your waking life that you previously found cute or harmless but has now turned into a potential problem or threat. The fact that the creature tried to eat you may indicate that you feel vulnerable and helpless in the face of this situation.
Alternatively, the dream could also be a representation of your own anxiety or fear of something turning against you. The rabbit, which is typically a harmless and peaceful animal, may represent your own innocence or vulnerability that you fear may be attacked or destroyed by external forces.
